Following a severe head injury with extreme micrognathia and obesity, which airway technique is acceptable?

• A. Mask technique
• B. Awake fiberoptic intubation
• C. Direct laryngoscopy after rapid sequence induction
• D. Blind nasal intubation

Answer: (B)

Anticipated difficult airway in a head-injury patient with extreme micrognathia and obesity is best managed by awake fiberoptic intubation. This approach preserves spontaneous breathing and airway reflexes while you secure the airway, which is crucial when there’s a high risk of airway obstruction or failed ventilation. The flexible fiberoptic scope lets you visualize and navigate around the small jaw and restricted mouth opening, even when neck movement should be minimized, reducing the chance of cervical spine injury or ICP increases that can accompany difficult laryngoscopy under anesthesia. By performing the procedure with topical anesthesia and light sedation, you maintain control of the airway without deep anesthesia or paralysis, lowering the risk of hypoxia during intubation. In contrast, mask techniques can be unreliable in obesity with facial deformities; direct laryngoscopy after rapid sequence induction can lead to dangerous apnea and a difficult intubation when anatomy is hostile and airway control is uncertain; and blind nasal intubation carries high failure and trauma risk, especially with potential skull-base injury.
